A 3-meter long aluminum wire has a resistance of 0.22 ohms. If the wire is doubled in length but maintains its original diameter, what would be the new resistance?
💡 Hint: Consider how length directly affects resistance.
If a metal wire's resistance is measured at room temperature and then heated to red hot, estimating the resistance might be key. If the initial resistance was 5 Ω, what might it be after heating?
💡 Hint: Reflect on temperature's effect on resistance in metals.
